COMBINED STOVE AND WATER-HEATER- The Schedule referred to in these Letters Patent and making partv of the same. I f

To all whom 'it 'may concern:

Be it known that I, HENRY HOWARD, of Springfield, in the county of Hampden, and State of Massachnsetts, have made and invented a new and useful Combined Stove and Hot-VVater Heating-Apparatus;

and lI do hereby declare that the following is a full, clear, and exact description ofthe constructionI and operation of the same, reference being had to the annexed drawings, making a part of this speciicatior1in which-y Figure l is a side elevation;

'The object of my invention is to provide acombined cooking and heating4apparatus, adapted more especiallyto basement-built houses' vin cities, whereby, and

I from thesame `fire, the ordinary cooking may be done, and a constant supply of water-heated, and caused to circulate through pipes and radiators, so as to warm thevarious compartments oi' the house, when necessary; while, by a slight change in the arrangement of the stove, nearly all 4heat may he diverted from the water-pipes, and utilized in cooking, without very materially raising the temperature of the kit-chen.

The following explanation, in connection with the' accompanying drawings, will enable thosel skilled in the art to practise 1 ny invention. The part marked A represents the body oi'the stove, provided around the bottom vwit'h a stout rim, mi, instead of legs, which rim is designed torest on a hearth ot' brick, tile, or cement. Across the bottom of the stove run girders,m' m, to strengthen thesaine, for 4the support ofthe superstructure.

lis the vertically-sliding front-dotnet1 the ash-box L, held atvarious points of elevation by the swinging ratchet j and pin k, which latter' is attached to the` door l.

K is the ordinary horizontally-sliding coldardamper, by which the draught may be graduated.

l), iig. 4, is the removable top ofthe stove, so made `to facilitate arranging and repairing the inner parts oi' the stove. l 1 V fr ril r2 r are the circle-covers, formed as usual, except'that I continue the groove s quite around the circle, instead of .confining it to one spot, that the lifter may be inserted in the groove at any point,

tud "the cover always readily removed.

S is that part to be removed, in connection with covers r1 and r2, when a wash-boiler is to be applied.

B is thefunnel, whereou rests the elevated oven C.

b b are the door-frames or ends of the oven, to

which a a are the ordinary doors.-

B is the circular lip, whereby the smoke or stovepipe is connected. al

c c' are rests or braces. for the better support of the oven C.

g is a small side-door, comiminicating with the ashbox L.

j' is a larger side-door, communicating with the heating-chamber M.

n is a partition separating the ash -box L .from the heating-chamber M.

Below partition there is a narrow aperture, 7, through which are cleaned out the ashes and debris that gradually collect at the bottom of chamber M.

q is a narrow slide or trap closing aperture 7 I constitutes the grate-trame and bottom of the rebox, and is pierced by holes, and arranged as in figs. 3 and 5.

E is thegrate, made up of separate bars, u u1, dto., which hars are corrugated by a spiral groove, as in tig. 5, while at opposite ends they are connected by au ordinary dovetail, and thus secured by passing a pin, e, horizontally through the series, as in iig. 7, to pre vent relative displacement, which construction and arrangement give strength and opennessto the grate,

and at the same time allow each of the several bars to expand and contract without injury or'referencc to the others.

h t are the grate-spindles, ofwhich h' is but a continuatjon of .the central grate-bar u2, while the inner end ot' h is formed as in iig; 8, to prevent its rolling in the grate, where it is held by the forked piece t', in combination with a groovearound such spindle.

F represents the boiler, and in winter constitutes the fire-box. I make it ofan oblong forni, corrugated inside, and open at top and bottom, figs. 3 and 9. The four walls of boiler-'F are hollow, and form a complete aud continuous shell, open only at the two points where connected with heating-pipes 1 and 3.

h thus arrange ribs, h

I make the inner and outer plates z' z, `of boiler F, about two inches apart, midway from top to bottom. I provide a horizontal partition, 8, dividing the boiler into two compartments, connected only bythe narrow opening 9 near the centrev of the front side, so that water introduced into the boiler from either of the rear openings must circulate quite around the rek to the front, pass through opening 9, in partition 8, and again circulate around the fire, to Afind its way out of the other rear opening.

G is a removable fire-box, corrugated, and provided at the top with a thin rim,- and placed in summer inside of' F, to shield it from heat.

c' is a partition near the rear of the stove, provided at top and bottom with. horizontal apertures, 19 and 20. Aperture 19is closed by an ordinary vibrating damper, e, and when so closed, heat from the lire-'box is forced in the directions indicated by arrows 10 and 11;

`When 'damper e is tilted against the back of the stove, as shown by the dotted outline in fig. 3, heat from the fire-box takes the direction indicated by arrow 12, without materially affecting chamber M, or the pipes therein.

l The oven C is made up of three cases, C C 0".' The space of about one inch between the outside and middle cases C C', I fill 'with a paste of plaster of Paris and water, by pouring the same, mixed as thickly as will readily run, between such cases, and allowing it to harden there, and theplaster beingr a non-conductor of heat, the temperature of the oven may be easily raised without Amaterially affecting that of' the kitchen. The space of about two inches between the middle case andioven proper, C C", constitutes the flue around the same. .x

y' is a vertical 'partition through funnel B, and d is a sliding damper at the bottom of the same, which damper, when arranged as' in iig. 3, allows the heat to escape in the direction indicated by arrow 13, but whensnch damper ispushed back against the rear of funnel B, then the heat is compelled to traverse the direction indicated by arrows 15, 16, and 14.

The parts marked 1, 2, 3, 4, 5, and 6, figs. 3 and 5, are pipes, in which, atteileaving boiler F, the water is heated while on its passage to and from the radiators H H', each of which' pipes performs a circuit, and is connected at opposite sides by a right-andleft connection-nipple, t, with other pipes, or with boiler F, and another pipe. The two lower pipes, 5 and`6, rest on bridges, w w', and those above are held in position by pins or rests, x x, 85e.

H H are the radiators,whereon the ribs h h" are 'so arranged as to' break joints on opposite faces,

fig. 11, while on opposite sides of the same face they stand the thickness of a rib out of line, fig. 12; and I h", for the purpose of ret-arding and more thoroughly heating the air that passes between such radiators, stacked as in fig. 11, and held together by a central bolt, a.

I make the body of the radiators H H hollow, as in fig. 12, thereby compelling the water to circulate around and through the same. Through cach radiator`are connection-apertures, ol o, around which apertures, on the respective faces of the radiators, are male and female seats, fitted to each other, as in lig. 3.

The practical operation of 'my invention is as. follows:

I connect any convenient number of radiators, properly stacked and arranged, to the heating-pipes 2 and 5, by means of ordinary pipes, n and o, taking 'care the same as other stoves.

that the bottom of the radiators be at least as high asthe top of boiler F, and that pipes, n and o, enter vsuch radiators from opposite sides, and at the top and bottom respectively, assin fig. 3. Each radiator having four apertures, it will be necessary to close one of such apertures in each of the outside radiators.

And further, I connect pipe o to an aqueduct leading from an ordinary reservoir of water outside of the house, or to a reservoir of water in the upper part of the house, by means of pipe P, and let water flow in freely, filling pipes, boiler, and radiators, which are then in pipes 1, 2, 86e., but immediately the ,water is heated it naturally begins to rise, and passes' out-ot` the boiler F, circulates around and through .pipes 1 and 2, thence through pipe ninto the radiators H H'. Becoming cool, it sinks hack through pipe o, and into pipe 5, where, warming, it passes through pipes 5and 6, 4 and 3, andthus back into the lower compartment of the boiler; but partition 8 compels the water to flow quite around to the front before it can rise through the opening 9, when it again flows hack and re-enters pipe 1, and thus continues to circulate.

In summer, when hcat is to be avoided asmuch as possible,` I place the box or lining G inside the boiler F, and tilt the damper e back, by which arrangement the water in the boiler and pipes is but little heated, while the non-conducting casing ofthe oven prevents superliuous heat to a great extent.

I consider a principal feature of' my invention, the combination of a removable fire-box lining, G, with a firefbox boiler, F.

For cooking-purposes the operation of' my stove is The hollow parts herein described, I cast on cores. The other parts are cast and connected in the ordinary manner.

Having thus described the construction and operation of my combined stove and heating-apparatus,

What I claim therein as new, and desired tosecure by Letters Patent,is-

l. The boiler F, constructed with 'partition 8 and aperture 9, substantially as herein described;

2. The dumping-grate E, composed of' a series of separate bars u u, 8m., connected laterally by a dove-- tail device, and secured at one end by a rod, V, as herein specified.

3. The stove-cover r, provided with a continuous groove s', as herein specified.

4. The removable fire-box or lining G, made of` any suitable material, in combination with the boiler F, substantially as herein specified.

5. The radiator H, provided with two connectionapertures o1 o2, and connectingbolt n', arranged, with reference to pipes nv and o, as herein specified.

6. The series of heating-pipes 1, 2,8m., when constiucted and arranged, with reference to pipes n and o, and to the boiler F, as herein specified.

7 The central partition i in combination with the funnel B, horizontally-sliding damper d, ovcn'and casings C C' C, as herein specified.
